Abstract
An elecrtrostatic separation of paper- and synthetic plastic material-containing mixtures is performed by comminuting the mixture, triboelectrically charging the comminuted mixture, and supplying it into a free-fall separator, wherein a paper-enriched and a synthetic plastic material-enriched fraction are produced, and in some cases they can be treated in a second electrostatic separation step to pure products.
